Description
Technical field
The utility model relates to a kind of novel anti-swirl baffle, belongs to the mechanical equipment field.
Background technology
Anti-swirl baffle is the vortex breakdown device again, is to be installed in liquid discharge nozzle place, to sedimentation and lock out operation, prevent that two mix (liquid-liquid phase, liquid-gas phase) mutually and flow out, and can obtain good result to eliminating vortex etc.
The effect of installing anti-swirl baffle:
When liquid outflowing container or tower bottom discharge nozzle, can form a downward whirling current at tube hub, make in the container each mix mutually and flow out, therefore be necessary to install anti-swirl baffle, its effect has:
1) can prevent on the liquid level to make pump depletion in the gas suction pump;
2) prevent to influence end product quality, and pump is stopped up because of eddy current flows out impurity in some liquid;
3) eddy current can make the bed separation of sedimentation separation and liquids having different specific weight degenerate, and therefore general liquid phase separator exit all is equiped with anti-swirl baffle;
4) can reduce gas in the tower because of eddy current by tower at the bottom of the loss that leads out of liquid;
5) sometimes for the stable operation of liquid level in container or the tower, also can adopt anti-swirl baffle.
The condition of installing anti-swirl baffle
The size of the installing of anti-swirl baffle and discharging caliber and liquid level are from the distance dependent of discharging ozzle.Obviously, discharge nozzle is more little, and the degree and the possibility that produce eddy current are just more little.
Generally, for discharging caliber DN＜50mm, if when not strict, can install to the requirement of anti-swirl baffle.The difficult more deeply more generation eddy current of the distance of minimum liquid level to ozzle.
The condition of installing anti-swirl baffle can determine by following formula:
In the formula: A---the distance of the minimum page to ozzle, m
DN---nominal pipe diameter, m
V---through the flow rate of liquid of discharge nozzle, m/s
If actual minimum level is less than computing value A, then considered is installed anti-swirl baffle.
In addition, according to engineering experience, as one of scenario, also should be at the discharge nozzle place installing anti-swirl baffle:
When 1) container bottom directly links to each other with pump intake;
2) need prevent that vortex from taking container bottom impurity out of, in the time of can influencing the liquid outlet of product design or deposition, obstruction back production system;
3) need carry out the container bottom outlet (, improving the effect of separation or layering) of sedimentation separation or stratified liquid in order to stablize liquid level.
According to the 9.2 anti-swirl baffle basic structures that provide among the HG20583-1998 " steel pressure vessels for the chemical industry structure design regulation " as
Mainly contain two kinds of structural shapes, wherein a kind of for discharge nozzle flushes with the welding of equipment inwall, be applicable to clean liquid.Another kind is that discharge nozzle stretches into device interior, is used for having the liquid of the beds of precipitation more, and discharge nozzle stretches into device interior; The dirt that can prevent accretion in the liquid, impurity or influence product design is brought in the pump; As required, when adopting this structure, should on equipment, establish a liquid discharging hole in addition.
There is the problem of the following aspects in the tradition anti-swirl baffle:
1) at first structure is on-disconnectable structure, when containing poly-mer in the medium, is prone to stop up, and is inconvenient to clean.
2) although be the media problem that the beds of precipitation are arranged of having considered of demountable structure, do not have filtering net, have partial impurities in the practical operation unavoidably and sneak into discharge nozzle, so that influence in product design or the entering pump.
3) because the discharge nozzle in the demountable structure stretches into device interior, thus discharging hole must be established in addition on the equipment, as do not have, need establish one in addition, increased device aperture quantity.
Device aperture not only can make equipment integral intensity weakened, but also can cause the higher stress concentration of the local appearance of verge of opening, has increased the possibility of equipment failure.
Summary of the invention
According to the deficiency of prior art, the technical matters that the utility model will solve is: a kind of novel anti-swirl baffle is provided, be difficult for stops up, the convenient cleaning, prevent that impurity from sneaking into discharge nozzle, influence product design or get in the pump minimizing device aperture quantity.
The utility model solves the technical scheme that its technical matters adopted: a kind of novel anti-swirl baffle is provided; Comprise steel pipe, cover plate and baffle plate; And assembly welding is one, it is characterized in that also comprising anchor fitting, and steel pipe is connected with anchor fitting; Evenly be provided with boring on the steel pipe body, steel pipe socket is in the baffle plate outside.
Evenly be provided with boring on the described steel pipe body, and be enclosed within the baffle plate outside.
Described anchor fitting is made up of through bolt is affixed two orthogonal back plates.
During use, back plate, steel pipe, cover plate and baffle plate, and assembly welding is one, is arranged on the discharge nozzle place, evenly is provided with boring on the steel pipe body, the steel pipe body is provided with anchor fitting.
Anchor fitting is fixed in discharge nozzle place through bolt with steel pipe by two orthogonal back plates.
Through the setting of anchor fitting, make and can novel anti-swirl baffle be dismantled that convenient the dismounting cleaned.
Steel pipe is provided with boring, can effectively stop impurity to sneak into discharge nozzle, influence in product design or the entering pump, and the steel pipe rigidity is big, and is easily fixing, is not easy breakage.
During use, discharge nozzle flushes with the welding of equipment inwall, needn't establish discharging hole in addition; Reduced device aperture quantity, fixed mount connects steel pipe, other end connecting device inwall for one section simultaneously; Reached the purpose that the utility model is fixed on the equipment inwall like this; Material flows into steel pipe through boring, arrives discharging opening then, is discharged to next operation at last through baffle plate again.
The beneficial effect of the utility model is: on the basis that keeps original function; Convenient cleaning, replacing, and prevent that effectively impurity from sneaking into outlet pipe influence product design or get in the pump; More reduced device aperture quantity, made equipment integral intensity unaffected.
